How to Use Japanese Whetstone
Sharpening instructions
1) The stone should be soaked in water for 3-5 mins before use and should be kept wet throughout the sharpening process by sprinkling with water, which acts as a lubricant on the stone. Dry with paper towels or newspapers.
2) The knife blade should be kept at an angle of 15-20 degrees on the stone.
3) During sharpening, whetstone powder will appear, but do not wash or wipe off this
residue and continue sharpening.
4) Knife blades with a double edge should be sharpened 50% on the front and 50% on the back. Knife blades with a single ground edge should be sharpened 90% on the front and 10% on the back.
5) When sharpening is complete, wash the knife in hot water and dry it thoroughly.
